That's man wearing nothing but a wing suit and those are the 460 feet tall ventura corporate towers in rio. You might want to hold your breath. Watch again as he descends through the mist and then -- he threads the neeld, 36 stories up and a gap dhat's 26 feet wide. Who is this? Jokke sommer and frenchman ludovic woerth. It was more for me to do it just for the fun of it. I always wanted to do an urban wing suit flight. Reporter: They took to skies at 5:45 a.M., Giving them 20 minutes before the first commercial flight would appear on the horizon. Then the leap. We just measured the distant from where we had to be dropped at what altitude. And how much the distance from this exact point to the building. Reporter: This is not their first daredevildive. They're careened through canyon, trimmed tree tops and rocketed past rocky mountainsides. How will they top this latest adrenaline ride? I would love to come to new york and fly. That is like, that is beyond my biggest dream. Reporter: The winged flyers landed in the nearly empty central square, celebrating that they survived the harrowing flight and that they caught it all on tape. Unbelievable images there. The margin of error was slim to none. A gust of wind could have taken them out completely. And the sound of them hitting the building -- because of the sound of them going through it? A gust of wind. They're -- feel free to not bring it here to new york. Thank you. Thank you for saying what we were all thinking.
